基于虚拟绕组的永磁同步电机谐波电流控制器舍入误差分析与补偿

Harmonic current control is a key research area in permanent magnet synchronous machines. The virtual winding-based harmonic current controller, as a novel approach, exhibits outstanding dynamic characteristics. To construct the virtual windings, this method requires delaying the currents by a fixed angle. However, since the actual delay angle must be an integer multiple of the switching period, r...
